- Review the specific terms of the repurchase agreement for the Series 2024A notes to confirm the final repurchase price and any associated costs.
- Assess the impact of the new convertible debt on the Company's overall leverage ratios and interest coverage.
- Confirm the conversion ratios and conversion prices for the new Series 2026A and Series 2026B notes to evaluate potential future equity dilution.
